But any bikes that did come out high will be first on the list for testing at the next available session and subject to the SAE figures and conversion figures generated by the Brands Dyno testing.

I ammended my earlier post and as far as the Parkitt Dyno goes we will probably be looking at a Class A figure of 60bhp (SAE) and a Class B figure of 49bhp (SAE)

I say probably as there is no intention of changing the stated limits in the rules which are Dynoject corrected DIN figures of 65bhp for Class A and 53bhp for Class B. Its just a matter of making sure the correct figures are used and applied to everyone

When the figures were incorporated into the rules they were considered a fair amount of horsepower that should be acheiveable by many and although money and a good tuner could get you more the series is not about who can afford the best tuner its about being the best racer and having a even and fair playing field

as the rules say
***Dyno Testing – when available the intention will be to Dyno test the top 3 finishers in each class and a few at random, if tested after race 1 you will not be tested again after race 2 instead the next highest finisher shall be tested.
Dyno testing is carried out at the bike owners risk and refusal to be tested will result in disqualification from the results for that meeting***

But you are using the results from Brands to "calibrate" readings. If this calibration exludes some machines tested as over-powered, surely they should be exluded from the results? Or will they just get exluded from future results? That is assuming there are people that were tested over the equivalent 53bhp.... but if they were, surely a line should be drawn and the exlusion start from day one?

btw, I don't know if anyone was tested over. As I say, I think mine was 48-49 (presumably the lower of the DIN/SAE figures, so equivalent to about 52ish adjusted?). I just think it would be useful if we knew where we stand, what calibrated dyno figure is the equivalent of our limit, and if there is any tolerance on that. For example, let us say it is 50bhp (unajusted), with a tolerance of +1?, so anyone testing over 51+bhp is disqualified. Because if Bradders was 50, a minor variation in contitions could see him creep over 50 (if that was the non-adjusted limit), but I don't think it would be fair to exlude him at 50-51, because it could just be tolerance in the test.

I know you haven't had time to properly look at it, but I think it would be useful to lay out the intentions of the test over the next few weeks so there are no surprises at Mallory.

was adjusted at 49 - 46 ish SAE ;)

and no one is taking my points over Craig without a fight!! :lol: :lol:

Sorry Bradders. The bike wasn't important anyway, just the intention.

:lol: dont need to apologise...it had 60 really but as you can see I influenced the dyno man with advanced use of Midi-chlorians

Skids... we need a new rule about mind control....

if a bike has no illegal parts and no illegal modifications, is it possible for it to be over the limit? and if it was, what could you do about it?

Quite right, dyno's and conditions can easily have a difference of 3 to 5 bhp for me at least 3 bikes should be checked and the average used. One or two bhp gain is not going to put you on the top step, its all about bottle in the corners and braking. Jimbo has not touched his in 2 years prob way down on power but he rode the arse off it.

I agree with everything said Phil. My point is, what are the results going to be used for? So, we get an average (or even a highest figure)... What do we do with it? As it happens, i don't think there are any illegal bikes, but I'm trying to work out the point of even bothering to stress the bikes on a dyno after a race if we have no limit or any intention of excluding anyone based upon any testing. If the intention is to exclude people based upon a figure determined from the Brands test, then I would like to know what it was and how my bike compares to it.

There were also a few other people like myself that put their bike on the Dyno before the racing. So there should be a good sample to understand how it compares to other Dynos.

The competitors who had their bikes tested should be told the results of their bikes. Is there a ceiling for where the bike is reved to? I would hate anyones bike to suffer an issue on the Dyno.

I feel sure this will sort itself out at Mallory.

Mark.

Just a point to how futile this dyno business is, how many class A bikes were behind the class B bikes with circa 10 plus more ponies.

Where as some had enough power to rip apart chains! (sorry Phil!)

PMSL very good

at the moment the rules state a maximum BHP, the rules are the rules are they not?

Very possibly Matt, but how would you feel if you had yours dyno'd at your favourite tuning shop & its right on the button for max hp.

You win your race and the circuit dyno says its over the max allowed by a good margin, your disqualified.

5% inaccuracies/descrepancies are the norm not 0.5%, as has been mentioned.

I tend to agree Phil. If so, what is the point of testing or having a bhp limit? The rules disallow tuning that would get you over the stated figures, so just check there are no mods against the rules rather than flogging an already stressed bike on a dyno. That is kind of the point I'm getting at. If we can't decide on a limit or tolerance, then we won't disqualify anyone, so why even bother testing?

I would be interested to see everyones results though.

The bottom ends (being basically the same as the 4 valvers) should all run to 10k without undue stress, and as the carb'd engines run out of usable power above 7500rpm, and the injected bikes not much over 8500k, there shouldn't be any reason to run higher than 9k on a dyno run ....
